How caregiving situations relate to preschool children's development, sensory profile, and sleep

Developmental Status, Sensory Processing, and Sleep Quality in Preschool Children Across Different Caregiving Models

Observational Fenerbahce University · NCT07511465

This project will see if 3–6-year-old children raised by first- or second-degree relatives, paid caregivers, or in daycare differ in development, sensory processing, and sleep quality.

What this trial studies

This observational study will enroll preschool children aged 3 to 6 living in Istanbul and compare developmental status, sensory processing, and sleep quality across four primary caregiving models (first-degree relatives, second-degree relatives, paid caregivers, and daycare). Parents will complete standardized tools—the Denver II for development, the Dunn Sensory Profile for sensory processing, and the Tayside Children's Sleep Questionnaire for sleep—along with demographic forms. Children must have experienced the same primary caregiving model for at least six months and cannot have prior neurological, developmental, or psychiatric diagnoses or be receiving related treatments. The study will analyze relationships among development, sensory processing, and sleep and test whether caregiving model is associated with differences in these outcomes.

Who should consider this trial

Good fit: Ideal participants are 3–6-year-old children in Istanbul who have lived in the same primary caregiving model for at least six months and whose parent or guardian can provide informed consent and complete Turkish-language forms.

Not a fit: Children with previously diagnosed neurological, developmental, or psychiatric disorders, or those currently receiving treatment for sensory, sleep, or developmental problems, are excluded and unlikely to benefit from this study's comparisons.

Why it matters

Potential benefit: If caregiving-related differences are identified, findings could help caregivers and local services tailor support to improve preschool children's developmental, sensory, and sleep outcomes.

How similar studies have performed: Prior research has linked caregiving environments to developmental and sleep differences and has used similar questionnaires, but head-to-head comparisons across these exact caregiving categories in preschoolers are limited.
